Pyrotechnics may only be enabled if and only if this terminal is shorted during launch day. It is crucial that this terminal is not shorted during the debugging stage of the rocket.
The Pypass terminal will ensure that the rockets main power source is not souly relying on the physical toggle switch. You MUST properly short this terminal during launch, not doing so WILL cause your rocket to malfunction and have a catastrophic failure.
Underneath each pyrotechnic terminal is an LED which will shine a very bright GREEN light when the terminal has continuity. This visual queue will let the user know that the pyro channels are LIVE and ready to go. Note that the LEDs can only show continuity if and only if the ARM terminal is also shorted.
Accelerometer based apogee detection will allow for high precision, non-environmental based apogee detection. Unlike barometric apogee detection, which has high noise, and is drastically affected by both light & temperature, the accelerometer based apogee detection only relies on gravity. By taking the magnitude of all 3 axis at any given time, it is almost guaranteed to detect apogee, since only a gravitational acceleration is pulled on the rocket at apogee. (The detection system includes uncertainty such as drift)
The rocket only enters flight mode if and only if the launch detection parameter is less than the current vertical acceleration of the rocket. The sensitivity (value) of the launch detection can be modified in the Cosmic Tower.
Using the Cosmic Tower (available on the Microsoft store), the user may change various paramters, this includes an apogee delay in the case the rocket enters high altitudes where the user may want the rocket to freefall. An apogee delay is also useful to ensure the rocket is indeed past apogee and has a lowest speed in order not to damage the shoot or apply stress onto the rocket.
